Eclipse was reckless and petty. Causing more of an annoyance towards his brothers. But his recklessness did show as he created a Wither Storm. Later on, he changed and became more manipulative and egotistical, often looking down on others, he considered inferior to him. Hes extremely smart but his ego is often his downfall as he underestimates his opponents and people around him. Hes controlling and self-absorbed, and often tries controlling those around him whether that be fear or tech he uses.
