Beast mode: Something similar to TFP Grimwing.
Weapons/equipment: Ironclad carries a sword capable of emitting waves of energy from it's blade, similar to the TFP Star Saber (though much less powerful). He also carries a talisman that can project an energy shield or serve as a digital assistant.
Bio: One of the ancient Knights of Iacon, an order of peacekeepers and explorers who left Cybertron millennia ago, Ironclad has returned to find that his world is now a very different place. He has allied himself with the Maximal nation (mostly on account of his beast mode and love for nature), and has dedicated himself once more to preserving peace across the planet. As one would expect from a knight; he is chivalrous, dutiful, and good-natured. He prefers to resolve issues peacefully, using his weapon as a last resort and for self-defense. This can be an issue, as he hesitates to fight or fully apply himself in combat.
