Undyne normally appears as a fish creature with silver armor. Her shoulder plates are golden along with the helmet's bottom half. Without her armor, she wears dark blue jeans with a silver tank top; with her base eye color being yellow. Undyne's pupils are black at default, however. She has a red ponytail and two fins on the side of her head, both red and blue.
Her scales her blue as well.
As the Undying, Undyne has black, purple, and golden armor. Her armor becomes layered and more spiked, with purple armor surrounding the waist, black being the majority, and golden being the heart on her chest and gloves, along with her usual shoulder plates. Her left eye flashes a red and purple spear, while the hand-held spear glows a deep blue/cyan. The tips on her shoes are gold-tipped. Her pupils and eye color also swap colors.
Undyne is extremely passionate with whatever it is she is doing. She acts very quickly on her own ideas and beliefs; and though she finds the goal of escaping the Underground a priority to the Monsters, she still plays fair with possible threats. She is extremely happy to mentor others in a variety of skills as well; as she is talented in combat and music.
- Undyne can turn the SOUL of any monster or human green; giving them a controllable spear to be used as a shield.
- She can summon EXTREME amounts of spears that vary in size, length, damage, and other variables. (Don't even.)
Undyne and Alphys are close love interests that have a close compassion. Undyne loves Alphys deeply and cares so much about her that'd she block a hit, as for anyone else she'd want to protect, for her. Even if it meant death in the process.
