Don't have much to post so far, but I do have some decent ones to say the least:
MECHA KLONOA:
Spoiler
Sorry but you are not allowed to view spoiler contents.
Mecha Klonoa is designed purely as a reference to the confusion newer Klonoa fans have by comparing him with Sonic characters, hence how I decided to design my own OC that was parallel to Metal Sonic, in that it's a robotic doppelganger to Klonoa. I had fun designing this thing since I actually had a good use for the long ears, by making them capable of acting as powerful, extra limbs with sharp claws. Also noted is that he has the "Metal Ring", which is on his left hand and is an evil counterpart to the Wind Ring. The Metal Ring has the same basic powers as the Wind Ring, but has the added bonus of being able to grab things that are armored due to Mecha Klonoa's increased strength. However, if he were to be a player character, he'd only do half damage by throwing things. He does 1.5x damage with his clawed "ears".
EMPERIUS:
Spoiler
Sorry but you are not allowed to view spoiler contents.
Emperius is a Legendary Zauridon designed in a set of 24 other Zauridons, for a total of 25. Emperius holds the record for being the largest Zauridon in terms of measurements, but is the third heaviest despite being so huge. Emperius stands about 120 meters tall, and is a hybrid of various Zauridons, using parts from Carnivosaur (Head), Triterrasaur (Horns and frill), Qdrasaur (Wings), Spinersuchus (Arms, legs, body, and sail), and Thoranosaur (Tail). The reason Emperius is only the third heaviest is because two other Zauridons have their own bodies composed of materials that are much heavier than organic matter (Dragora is made of Anti-Matter, and Grandis is made of an unknown metal alloy). Emperius, until you encounter the next few Legendaries in the set, is the most powerful Zauridon that doesn't require post-game unlocking. Emperius also makes a cameo in E.S.W.N. as a minor antagonist, and the optional boss of it's own dungeon, in which it has the largest sprite of any character in the game.
