Recently, I found an almost full box of Mega Construx Halo Heroes Series 10.
From my observation, here is the ratio in each box:
- Cortana – 2 per box
- Master Chief – 2 per box
- Didact – 1 per box
- Spartan Kat-B320 – 2 per box
- Tartarus – 2 per box
- Yap Yap the Destroyer – 3 per box
- The Rookie – 3 per box
- Arbiter – 2 per box
- Spartan Noble Six – 2 per box
- Prophet of Mercy – 2 per box
Personally, I am a fan of Didact figure and Cortana figure. This version of Cortana is a little different from the version of Cortana from Mega Construx Halo Heroes Series 5. She was blue in Series 5 and she is purple with different markings in Series 10.
Check out Cortana from Series 5:
As far as Master Chief goes, he appeared in Halo Heroes Series 1 (Mark IV Armor), Series 5 (Mark VI Armor), Series 8 (Mark V Armor), and now Series 10 (not sure which Armor, but he has a golden rifle).
