Well the older brother died in the first game...unless theres another older-older brother.

1. stop it withh all the subby threads
2.its the dk amulet, remeber..its making him older

Yea these storylines are starting to suck, they have subby getting older with each game that coems along, and reptile turning more well reptile as the sequels come on, damnit the more the sequels, the more we will grow to hate our favorite charcters cause their moves and stuff will get lamer, and they will decrease.

The medallion of the dragon increases the biological rate of that has it, which towards since in the MKDA it saw older, and if it has spent enough time and it has had to use much of the power of medallion, is normal that it is seen more aged of which really is.

This is not a rumor or theory, is real.

It's like Reptile. The more aggrivated he gets the more primal his form becomes. In MK4 reptile was ticked off for a reason, and In MKDA he was furious which made his body form and shape into a different reptilian style.
