Ladon

• Either color variant is fine. It changes depending on the moon phase. 
• He is very large for an umbreon. He's built like a tank

Ladon is a highly motivated and charismatic leader. Though he can be intimidating to those who don't know him and he radiates strength in his voice, actions, and choices. He always protects the innocent and puts those in need first. He can sometimes be temperamental (mostly if those he's trying to protect are threatened), but he always means well and rarely gets out of control. 

He has a commanding presence to strangers or threats, but to those who know him, he's a lovable and reliable stone wall. He never gives in, never gives up, and has dad advice for days (despite not being a parent, of course.) He loves to engage a bit of mischief here and there, and though he will never hurt people he definitely likes a bit of fun on the side of his more serious outer shell.

If he makes you a promise, you can depend on him to fulfill it, no matter what. If you show him respect and loyalty, you'll have a friend who will go to the ends of the earth to prove they've earned it. 

Ladon is not native to the sky island. At some point, he was the leader of a small rebellion of pokemon in a parallel world who were rising against another group who were committed to controlling legendary pokemon. He is an adept fighter, inspirational leader, and highly motivated soldier who never backs down from a fight. He and his band saved that world, but the commotion caught someone's eye...Myriad, a strange Mew from another dimension. While she investigated, another pokemon followed. Infinity; a very powerful, and very obnoxious pokemon that seemed to demand attention everywhere she went. Ladon had no cares for it, He had seen too much to care about power- it was what someone did with it that counted.

Infinity however, saw his lack of concern as a challenge, and dedicated her powers to winning him over, saving and repairing the world through monumental feats of energy unfathomable to Ladon himself. He... Didn't particularly care. At first, anyway. It wasn't until she gave up and just tried to genuinely connect with him that he truly opened up.

Though she still tends to be pretty loud and showoffish, they do have a deep connection. Ladon is more of a silent type, but can take charge when necessary. He finds her whimsical nature endearing, though he will certainly step in if she's getting carried away. He may not be as powerful as his partner, but he's most certainly got the intimidation skills to convince you otherwise 

After his own world's safety was guaranteed, he set about travelling the realms with Infinity, mostly...smoothing over her offending people.
