tiny thunderclash being the bestest boy, perfect cuddler, always trying to help with tasks. Thanks to size its a little easier to carry stuff to you, like pencils and maybe a fruit. He'll sometimes even give you coins he finds and drags tissues to you when he find you sad and will not leave you alone until you feel better.
Rodimus hates his guts. How DARE he be so helpful! Especially to him! How dare he help him onto the couch to snuggle with you. How dare he give him cool rocks he definitely doesn't keep because he's so insufferable.
Rodimus: >:[ he tryna steal my human from me and is hiding it by being nice to me! How dare he!
Thunderclash: I luv Roddy and human :3 I must give gifts! :D
Rodimus is usually a possessive lil teeny, but when Thunderclash is put into the equation he goes FERAL
Thunderclash will be the most helpful tiny ever. He will bring you items you need (if you think you lost something, no you didn't, because Thunderclash knows where it is), remind you to restock on something if you run out, help you organize stuff. He's a very good boi.
Roddy feels threatened by this behavior and will do everything in his power to inconvenience Thunderclash at every turn. Unfortunately, Roddy is usually not the best at executing these, and Thunderclash generally takes them as misunderstood attempts to be friends.
It's a wonderful dynamic.
