Time Master

Tmeliner (known as タイムラインの攻撃の攻撃 Taimurain no kōgeki no kōgeki, lit. "Timeline Assault Attack" in Japan) is a "tactical 2D action RPG" made up of overrated characters for the latest Nintendo systems!

Before era
The story starts with an old man named Ryoko (meaning "traveler") who is putting up a "get together" and goes through different Worlds to invite his friends! Only the first World can be visited and after it's complete the other ones become available (Yoshi's then Pokemons'), and when they're completed the rest becomes available, too!

Chuck's (Sonic's) World
Ryoko goes to Chuck's World (before his roboticization) where he finds several enemies called "Splicers" ("Chromers" in the Japanese version) and he begins to fight the off. After defeating all of the enemies and the boss he gives Chuck the invitation letter, then teleports out of the World.

Yoshi's (Mario's) World
Ryoko goes to Yoshi's World where he once again finds the same enemies. Confused and angry he finds them off and gives Yoshi (with Baby Mario on his back) the invitation, then teleports.

Pokemon World
Ryoko goes to the Pokemon World where he yet again finds the same enemies. After he, yet again, defeats all of them oof he took a moment to think about why all of these Splicers are appearing. He gives the Elite Four (from the Red and Blue versions) invitations, then teleports. After this point it's just the same old routine, but I'm gonna let you in about who he give the invitation(s) to who.

Link's Uncle's (Link's) World He gives the invitation to Link's Uncle.

Kirby's World
He gives the invitation to (the younger) Kirby.

Samus's World
He gives the invitation to (the younger) Samus Aran.

2ndD (2nd Dimension for short)
This becomes available once all the other Worlds are completed.

When he finally figured it out he goes to the 2ndD to fight Gigas, the time king. You have to go through 5 Floors to fight Gigas, but there are 60.0% chances that the Save & Shop Floor will appear along with a 22.5% chance of the Treasure Floor appearing. You finally reach the Last Floor where you say that so many Splicers appear because they where attempting to alter all of the Worlds!! And if it weren't for the idea of a "get together", Gigas would've had the whole universe in his hands by now! You then face off against him (Note: He's really tough). Win or lose Gigas begins to unleash a swarm of Splicers to the universe! But suddenly he get the idea to sacrifice his life and Self-Destruct on Gigas. He's dead, the swarm dies down, and Gigas survives, but Gigas is left with a fatal injury.

Meanwhile back at Ryoko's place the "get together" was taking place... But Ryoko never showed up...

Classic era
A boy named Shindo (meaning "prodigy"), Ryoko's grandson, is born in 1989 and in 1999 becomes 10 years old on his birthday! While playing Sonic Adventure on his Sega Dreamcast (which just came out back then) during the Emerald Coast stage with Sonic being chased by a giant orca Sonic pops out and grabs Shindo's left arm and pulls him in to another universe!!

Sonic's World
Shindo, who immediately freezes from the sight of another World, starts freaking out then calms down. Shindo asks Sonic why he's here. Sonic says he has a "gift." He has the ability to channel from his universe to another. And the VG universe is in danger!! Shindo agrees to help to save the universe. Then a Tutorial starts (you have tthe option to skip it). After many minutes of "Tutorific" gameplay Shindo and Sonic goes on to help Tails, Amy, and Knuckles (respectively). After reaching the Final Floor you see a Master Emerald. Shindo approaches it, but suddenly!... It shatters... It was Eggman!! He shattered it by shooting the beam at it. Then he uses the Egg Scrambler Machine (I know: Ironic isn't it?) a.k.a. the E.S.M. to send the Master Emerald shards across the universe. Then you face him and defeat him. Sonic and his friends thanks Shindo, and Knuckles teaches him how to teleport: He just focuses on the place he wants to go and BAM! He's there.

Mario's World
At this point you can now access several other Worlds, but going here will bring up more Tutorials, but that'll be explained later.

Shindo arrives at Mario's World where he finds him surrounded by Splicers and attempts to rescue him. Now for the Tutorial!: You have to rescue people from being alternated, and the "rescue missions" are treated as Floors (which explains how Sonic's friends opened Floor Steps). After battling an enemy (doesn't have to be KOed (KO'd in the Japanese version)) and it's Mario turn he defeats several surrounding Splicers with a spin attack. Mario then moves on to catchup to ya'. After defeating all enemies Mario shakes Shindo hand as a thank you, then they move on to rescue Mario's friends. You'll obtain a Master Emerald Shard from Yoshi (collect them all and the Master Emerald will be restored! There will also be a secret Superbosses after you put them all back together...!) if you rescue him (he found it while traveling). On the final floor you'll face off against Bowser and defeat him! Mario and his friends thanks you and you teleport out of their world. The same cycle (aside from the Tutorial. All the bosses on the Final Floor are also the bosses of their respective World) on the other Worlds continues from there until the last World (aside from 2ndD) when a cutscene kicks in prompting that 2ndD is now available to enter.

2ndD
As said above a cutscene on the last World aside from this one will prompt that this world is now available to enter. There are 10 Floors this time and as you reach the Last Floor you see Gigas injured. He saids that he wants you're power in order to recover and take over the universe!! You then procced to fight him. After you defeat him you seal him with your power. Then everything's back to normal! You return to your own universe to relax.

Modern era
It's 2003 and the Dreamcast discontinued 2 years ago!! You're 14 years old. You just started High School. And when you opened the door...you see Sonic, Mario, and the other video game characters from the World you went to!! Shindo asks them what the heck they're doing here. Sonic saids that no one but him can see them. Then they teleport you to their universe.
