Here's the next two, my Earth Skylander and Air Skylander. ...Something didn't work right for Static Wing. He looked so adorable on paper, but redone in paint he looks like a shell of what he could have been.

Name: ThunderBrella
Element: Earth
Description: ThunderBrella is a massive Mabu with a razor-tipped parasol. She is particularly strong, brave, and she never backs away from a challenge, carrying personality traits that are rare in Mabu. Her strength is enough crack the earth. She can also transform into a statue.
Basic Moves
1: (Strike Up) She strikes the ground, scattering debris at her opponents.
2: (Guard) She can do one of two things. With her umbrella, she can guard against attacks. Without, she turns into a statue to defend herself from damage, and can shatter her statue to scatter stone shards in close proximity.
Basic Upgrades
1: (Brella Power) When guarding, she can release a powerful charging shot from her umbrella.
2: (Earth Cracker) Thunderbrella's Strike Up move is stronger and effects a wider range.
3: She throws out her umbrella and it spins like a top for a limited time or until she calls it back. She can move and attack during so, and the umbrella acts as a big obstacle.
4: (Pinwheel) Brella becomes stronger and better at guarding.
"Shake and Quake" upgrades
1: (Earth Shatter) Thunderbrella strikes the ground harder with Strike Up, spreading even more and powerful debris.
2: (Breakthrough) Thunderbrella's statue form effects a wider range after exiting from the statue.
Soul Gem: No idea yet.
3: (Heavy Thunder) Thunderbrella's massive frame causes the ground to shake, which slows down opponents.
"Brella Defenda" upgrades.
1: (Super Shot) Thunderbrella's force blast is more powerful and bigger.
2: (Blade Brella) Thunderbrella's umbrella can do even more damage when released.
3: (Porcupine Parasol) Brella can shoot needles when spinning.
Soul Gem: (Rollin' Rocks) The debris Thunderbrella summons after Strike Up roll forward, covering more range.
Other: She is the same Mabu variant as Hugo, but is not related to him in any way. Se is also partially based off of a tanuki. And, yes, she's supposed to be female. Also, although it doesn't appear in this drawing, her umbrella is actually a living creature. Under the umbrella, there's an eye and a mouth that reveal a living being.

Name: Static Wing
Element: Air
Description: A static-prone bat who can use electricity to attract objects which he uses to attack. He can also use his own electricity to attack.
Basic Moves
1: (Material Summon) Static can summon large objects to cling to. They cannot do damage on their own but Static can use them with his other attack.
2: (Attract) Static Wing sends out a shockwave which will attempt to attract his objects. If successful, he uses attracted objects and can send them at opponents to deal big damage. If not, he sends out an arcing bolt of lightning that's really hard to dodge. Both can hurt opponents.
Basic upgrades
1: (Extra Summon) Static Wing can summon a few more items.
2: (Static Spin) Static spins around rapidly, creating a tornado around him that sucks in his objects and sends them outward. Path is random.
3: (Flying Debris) Summoned objects can fly faster when thrown.
4: (Lightning Strike) Static Wing's bolt after his attraction move is stronger.
"Factory Bat" upgrades.
1: (Mass Produce) Static Wing can summon even more upgrades.
2: (Whirling Waste) Objects flung by his whirlwind go circling outward, making them potentially harder to dodge.
3: (Garbage Disposal) Static Wing can charge up to fling all objects at once. The more objects, the stronger, but slower the attack.
"Zappy Zappy" Upgrades.
1: (Shockwave) Static Wing's attraction field is stronger and spreads wider.
2: (Crashing Thunder) Static Wing's lightning bolt is even stronger.
3: (Cloudy Catastrophe) A cloud looms over Static Wing, and when he does his lightning strike, the lightning strikes the cloud, which summons THREE bolts instead of one.
Soul Gem: (Shocking Cyclone) Static energy builds around Static Wing when doing the Static Spin, dealing damage upon touch.
Other: A bat because I adore bats. This guy is also supposed to be a character who's not too strong, but uses high-accuracy moves to make up for it. Also, his name is a play on the phrase "Static Cling" as well makes up the general idea for the character.

Updated both.
