The need for Boulder's Sceptre to fully charge Magma's ultimate one is all forgotten near the end, when Magma achieves this.

While it makes sense to send one Command Centre to stealthily sneak past Rogue Star. Why though did Leader-1 not take additional Guardians with him on such a mission. Out of a crew of five, he and Turbo are the only actual combatants.

Rogue Star is a massive command ship, that manages to steer its way through an asteroid belt. Yet the Guardian Command Centre; a much smaller and more agile craft, manages to hit enough asteroids and crash.

The Renegade scientist; Herr Fiend, is present among the Guardian Council during the Renegade attack on Gobotron. Yet, when he does appear later aboard Rogue Star, he has been replaced with the Guardian Baron Vonjoy. Yet still speaks in Herr Fiend's voice. This was likely due to a mix up in the character model sheets.

Shouldn't Nugget have still informed the Guardians on how to safely navigate the asteroid belt in orbit of his planet? Considering the Guardians had never been to his world and would be unaware of such a dangerous obstacle.
