Beta 4

Beta 4 is a planet in the Generation 1 continuity family.

Beta 4 is five planets up from Beta 9. Kup has been to both, apparently, and fighting Scourge and Cyclonus seems to remind him of one of his battles at either planet. According to Kup, Beta 4 has some incredibly thick dust and is inhabited by Ick-Yaks.
