If that were a real game I got quite an interess into it.
If it exist, I would create this character:
Class: ??? (Idk what to put, since I use a learning type power, non-robotic, and his style is close range)
- main sub-abilities:
* speed (Used for dodging, or get into position to use learn or counter)
* learn (any type of attack used on this character can be used, but leaves the character wide open to attacks, and can't use counter)
* counter (Can't be used with learn, takes any attack and returns it back to the opponent)
(Limits to learn: Can hold up to permanently up to 4 attacks, an attack can be changed if learn is used again, but only after the battle if won, for each 5 levels the limit of attacks is up by 1. Level 50 is max for number of attacks he can learn, but gains the ability combine (fuse 2 or more different attacks to make one extreme attacks)) (note: by attacks, I also mean heal, defence, etc.)
Type of training: Defence/Endurence and Speed
Hacker: Yes, but has a safe lock hack that prevents his character to be hacked in any way. Even from virus and bugs.
Personnality & Biography: Loves to try anything new, hates to hack except to protect himself, works legit, he tends to go help especially against hackers and unknown bugs. He learn quickly so he hates to get the obvious out of anything. Loves to wordplay, so he also ends up doing poetry. (Got my own personality to it too)
I will be shock to see this character used... well more surprised but happy.
And I bet, that many more will love to see a game like in your animation exist.
