Powers and Abilities
Rak's strength has never been explicitly commented on in relation to others thus far in the series. However, it is highly apparent he is far stronger than an average E-rank Regular in Part 2, during the Workshop Battle. Of particular note is the fact he is assigned a price of 150,000 points in the Development Tournament of the Workshop Battle, same as that of Yeon Yihwa and more than that of Quaetro Blitz. This is even more impressive when you consider that he was of unknown reputation and participated in the prior rounds of the Workshop Battle solely in his compressed form, which weakens his strength.
Immense Strength: Rak is extremely strong, disproportionate even with his huge size. He was able to throw a spear over a huge distance and smash aside multiple "strong" Regulars. In the Last Examination, he jumps off a tall cliff while carrying Parakewl through a vast distance and lands on a Giant Worm, with apparently no injury to himself whatsoever.
Spear Expert: Rak can wield his huge spear at both close range and long range with excellent skill. He can hit small targets that are hundreds of meters away, as shown when he hit a sniper rifle right out of a gunner's hands in the Crown Game, despite them being on the other side of the arena. He was able to swing and thrust his spear at close range so fast that even Koon was only able to find an opening when Rak was distracted.
Hunting Intuition: Rak has a sense or feel for strong opponents or weapons like the Green April or the Black March.
Compression Licenser: Beings with sizes inconvenient to move about the Tower can get permission from officials to have their size reduced drastically. This allows Rak to become smaller at will.
Rak's Shinsso quality takes the form of a stone shield.  In order to save Koon from an attack Rak has already shown the ability to manipulate Stones.  After Rak has eaten lots of stones, his hands turn into rocks or they slowly start to attach to Rak's hands. 
Spear: This is the spear he's been using since the 2nd Floor. He uses it throw, slice or pierce and it is apparently important to him probably because he's been using it for so long. Though he ends up exchanging it for new weapon named Mad Shocker.
Mad Shocker: It is a throwing spear that changes shape as it is thrown and has a higher destructive power than a normal spear. It is likely to be at least an E-rank weapon considering his current level. The spear is good for both offence and defence.
