Help naming these 2 old games!

Hi, there's 2 games that have been on my mind recently, which i used to play many years ago.

The first was for the PS1, it was a overhead figher, you'd fight in like a arena, you'd be monsters, i can remember one was like a scorpion so you could call it a "Party" fighter?

The second is for the Gamecube, it was a racing game similar to Mario Kart, but i only remember battle mode as that's what i used to always play with my freind, i can remember the graphics being cartoony, and that one of the weapons you could use was a spear which would pin the other kart to wall.

If anyone could name any of these, it'd be greatly apprecicated, because theyve been doing my head in!
