bolts lost - ringo and di

some characters that i planned for a own story called "bolts lost" but i don't think i'm going to make any comics or anything of it. 8D but still, i could tell about these characters something. xD

name: ringo.
age: 19 years.
gender: male.
species: smellyell. (yes, i made it. shuddup.)
nature: ringo is little bit nuts and can get really wild but still it's possible for him to stay calm. once he decides to take care of something, he will not easily let the protected down.
abilities: good stamina and jumps high, but doesn't have any special abilities expect his smell he can use to keep enemies away. when fighting he will fight without any weapons, but sometimes can use a metal pipe.
past: ringo lived in a landfill where he had a nice little cottage, but nobody knew that ringo had a big secret. he had created a giant robot what could be really dangerous in anybody else's hands than ringo's himself. one night when he was walking outside he found a little wounded dog in the rain. when he looked closer ringo noticed it had somekind of wheels what we're broken so the dog must be a disabled person. ringo decided to carry the dog to his cottage. when the morning came and ringo got to know something of this dog called di, ringo noticed that the giant robot was gone! di told ringo that if someone stole it, the robot was probably at the city. so ringo's and di's adventure begun.
else: ringo is pretty good with technology.

name: di.
age: 18 years.
gender: female.
species: dog. breed unknown.
nature: di is mature wise lady but is pretty short tempered.
abilities: haven't came up with anything so suggestions would be welcome. 8'D
past: di lived in the city for long time, but when her parents died she didn't really know what to do. so before anybody would know of their death and take di away she escaped from the city with her new wheels she used to move. for year she kept traveling until she arrived to a big landfill. her wheels broke and she wouldn't move at all. nobody heard her yelling so she had to stay there. then ringo found her at night and took to his cottage. when waking up in this strange cottage she finally met ringo, his new soulmate.
