After Terry kills Geese in Fatal Fury whatever he takes Rock as his adoptive son, raising him and teaching him how to fight, because he feels bad leaving him an 8 year old orphan. Rock hated his Dad because well, who wouldn't so he was fine with this. Rock therefore has a combination of terry's stuff (rising tackle, the dunk and burn knuckle like moves) and geese stuff (reppuken, deadly rave, counters, burst super)
IDK how he learned geese's moves when terry adopted him as a child either lolz
Why are you weirdos spoilering this shit?
Correct- although Terry didn't kill Geese- the official storyline ending for this is in the first Real Bout Fatal Fury. Geese gets knocked off the tower (again) and Terry catches him, but Geese lets go and falls, laughing the whole way down. There's then some scenes of Terry with Rock as a kid.
Kid Rock (lol) would also pop up in some of Terry's win poses in a few of the KOF games.
That's then the end of Geese in any canon story games. The Geese in Real Bout Special is "Nightmare Geese" (with a halo) and although Geese is a regular character in Real Bout 2, the game has no story like RBS.
What about Geese in KOF? The King Of Fighters games are their own thing and the stories are different. The KOF games also change character ages, since Art Of Fighting takes place before Fatal Fury and the AOF characters should all be somewhere between 10-15 years older than the FF characters.
The links between the AOF and FF games are pretty cool- SNK even tied Last Blade to these series as Zantetsu is AOF2 character Eiji Kisaragi's ancestor. In Art Of Fighting 2, a younger Geese Howard is the hidden boss. There's a blueprint for the same Geese Tower he'd later get knocked off of shown on his stage.
And then at the end of the Tekken 7 reveal trailer, it shows Geese falling and laughing in black and white. My take on this is that Geese in TK7 is him dreaming it all while falling.
