Boss Saimon are fast, sleek aliens that tend to be troublesome when attempting to complete quests for other aliens. They are the fastest Alien of the Lower Maps.
Boss Saimon are the four times stronger version of the regular Saimon and are hostile to passing players attacking on-sight. These aliens usually do not require many other players to defeat due to the low HP and damage of them.
The Boss Saimon is known for its base speed while inflicting steady damage over time. It has speed slightly slower than a Lordakia. Compared to a regular Mordon, it is slightly stronger and has stronger attacks while it is still half as powerful as a Boss Mordon. Rewards, cargo drop, damage, shield, and HP are all four times the normal amount and can be worth the time in the Lower Maps to hunt.
