I maintain my eldest party member status! Yes!
Also, starly is allowed? I thought no flying or normal types were allowed? I have no problem with it mind you...
So we have 2 pacifists of differing levels (myself and Kira) and two slightly deranged characters. I assume Kyle and Jonathan are taking the bulk of the battles while Bjorn supports with taking heavy hits for the team while training for league matches and hatching/breeding pokemon.
And taking a quick peek, only breedable guys we have (because I haven't check genders, this can be changed) is Ralts and Gastly (makes little sense, but same egg group). I also think if anyone has a rival they would know before they set out would be myself if we go with saying the guy I injure is my rival. It would also be hilarious instead of conflicting types, it was rather pokemon that are similar or opposite of eachother that were the starters. For example, gastly trainer's rival uses a cleffa, Ralts trainer goes against another Ralts but goes gallade/gardevoir instead, etc. It'd be harder for some.
I do actually want to know if we know eachother prior, because it would be weird working with people who don't know each other. I'm going to assume Kira knows Bjorn as the others do; big brother figure that gives away free pokemon, helps people train and care for pokemon, so its not hard to come across my guy as a stranger. Judging from how your character is, I'm going to assume Bjorn doesn't know much about Kira and while he admires her will to help pokemon in trouble, he is a little off-stricken by the fact that she has chosen to leave on an adventure. He feels he may need to be a little more protective of her over the others due to her pacifism exceeding his own (and Bjorn will avoid a battle if he can, but will not back down or flee if hes thrust upon one).
As for Grond, Grond is, once again, very relaxed and calm in most situations. He has the odd quirk of being hungry often and digging around a lot looking for sources of Iron and other raw metals (Which Bjorn usually has pieces of metal on hand for him to eat, with iron of course, being his favorite). He has gotten into trouble before for gnawing on pipes, siding and even railroad tracks, getting himself and Bjorn in trouble. Despite not seeing many of them, Grond has a slight anger problem towards certain males of the Monster egg group. Grond is believed to be very territorial in this aspect, but Grond won't attack unless provoked or given orders to attack. He has a big dislike of larvitar for some reason
