I'm not quite getting what the general idea for this one, but for some reason, seing Rayman, Banjo and others on here makes me think that Plok would fit pretty well here. Again, maybe it doesn't fit at all, but I think it's the perfect example ''Nice/adorable character that turns into an absolute menace'' as soon as his flag is stolen

Advance Wars 2 > Advance Wars: Day of Ruin
Tomb Raider Chronicles > Angel of Darkness
Metal Gear Solid 2: Sons of Liberty > Metal Gear Solid 4: Guns of the Patriots (Raiden)
The Sims > The Urbz
Tony Hawk's Pro Skater 4 > Tony Hawk's Underground
Spore > Darkspore

I think Leon would love to make this list for Resident Evil 2 > Resident Evil 4, but we all know he's kidding himself

I also thought about adding Leon to this but decided against it. We're on a very similar wavelength.
