Name these three brothers!!

These are my siblings adorable cats, I believe 8-10 months old? They're kinda hard to tell them apart haha so here is some info about them! I'd love warrior names for them even though they'd probably still be Apprentices haha

Callisto- The one with a black chin- he and his brother Cosmo are the hardest to tell apart by face otherwise haha. He's got a very fluffy face haha and is my siblings favourite (technically they're the 'family' cats but Callisto IS theirs) and is generally very cuddly and friendly

Cosmo- the one that looks like Callistp but without a black chin haha. Less fluffy face too and he also has a lot of white individual furs in his black fur like stars in space. Only really favours a couple people in that house I think haha. Has been to the vets today and has suspected to have been hit by a car cause he isn't eating and has been limping badly :(((

Pluto- the cutest one imo haha and easiest to tell apart cause his face is mostly black. Super adorable and more shy than his brothers. Was even thought to be a girl as first until my family sent him to the vet to get stayed so they didn't end up with more kittens and turned out he was just a prettt boy. Is more wild than his brothers as their mama kept him hidden and with her much longer so my mum has noticed that he walks in a more stealthy, nature way, compared to him prancing brothers lmao
