Bearing in mind I am your basic, natural coward

1) Underwater materia - That way I can just live at the bottom of a pond and hide from everyone

2) Fire Materia - I'll need to have something to complain about. I can just sit there and whinge about not being able to start a fire in my pond.

3) Odin Materia - Just for someone to talk to. He can tell me about lots of things... what its like in Valhalla, the reason why he has horns, tips for looking after his horse... then I can tell him all about my broken Fire Materia...
