Kul'dar

Supreme Commander Kul'dar is the leader of the elite guards and probably the former Emperor of Planet Gur'latan.

BoBoiBoy Movie 2
When Retak'ka arrived on planet Gur'latan with the intention of strengthening his elemental powers, he was met with opposition from Guruhan's Army. As soon as Commander Kul'dar spotted Retak'ka, he asked for his identity, but he didn't respond to Kul'dar's question and instead used his Voltra element to drain the planet's energy. Commander Kul'dar ordered his army to attack Retak'ka, hoping to bring him down and thus protect the planet's resources. Despite the army's initial efforts, Retak'ka was able to withstand their attacks and ultimately defeat them quickly. When Fang and Captain Kaizo arrived on the planet, they were surprised to find that the army had been defeated.

Personality
Kul'dar is known for being an exceptional leader as well as a loving father. In fact, he openly expresses his affection for his daughter Kira'na by ordering her to stay out of danger when Retak'ka's invasion is imminent. This decision shows that Kul'dar is fully aware of the grave consequences that he may face if he takes on Retak'ka, but he is willing to take that risk to ensure the safety of his loved ones. In conclusion, Kul'dar is a remarkable figure who prioritizes the protection of those he cares about the most.

Physical appearance
In the BoBoiBoy Movie 2, Kul'dar is depicted wearing a complete set of Gur'latan armor.

In Galaxy Season 2, he made an appearance in a flashback. During this scene, there was a detailed review of his physical features without his armor. Kul'dar is an alien with a humanoid appearance and has a well-built muscular physique. The skin on his body is dark-coloured. There are two scars on his face, which are situated on his left cheek and forehead, that resemble a lightning bolt. He has red hair and a beard followed by striking red coloured eyes.
