I was looking around the runescape pages and then i found this. Can you beat them all?(solo)
1. The Beast (corporoal beast)Most simply known as 'The Beast', this creature appears to be the manifestation (either spiritual or corporeal - it varies from source to source) of the souls of those who have died in the Wilderness. I do not know much of this beast, and even what I do know may not be the truth. It is, to my knowledge, the most powerful entity on RuneScape, by any measure.
2. TzTok-JadTzTok-Jad was, until recently, considered to be the strongest creature on RuneScape. Born of the volcano and treated with great respect by a race of obsidian creatures called the TzHaar, TzTok-Jad loosely translates to 'obsidian fire elemental'.
3. K'ril TsutsarothThe demon called K'ril Tsutsaroth, one-time leader of Zamorak's armies on RuneScape, is next. All demons have names, and they believe that names have power, so they choose not to share them unless they believe themselves to be so powerful that it does not matter if their name is known. In fact, if a demon earns a certain level of notoriety, they can actually garner more power through the intimidation that their name brings.
4. General Graador General Graardor is from a race of creatures known as ourgs, one of the most powerful races bred by the god Bandos. Ourgs had been thought to have died out over the course of numerous wars, until what is now known as the God Wars Dungeon thawed out and this (hopefully) last remaining general with it. There is some evidence of a zombified creature called Slash Bash somewhere in the Feldip Hills, but it has not been established if this creature began life as an ourg or was just an abnormally large ogre.
5. Commander Zilyana Although technically not a 'beast', the next strongest creature is Commander Zilyana. As with General Graardor, her race, the icyene, were also thought to have either died out or left RuneScape. Much knowledge of the icyene race has been lost to time, although I have stumbled across a number of references to one by the name of Efaritay. All I can garner is that she was an enemy of the vampyre nation.
6. Kree'arra The God Wars Dungeon once again provides us with a strong creature, though this one is also not a beast. Kree'arra is an aviansie, who, my books tell me, were the most beloved race of the god Armadyl, though they were thought to have been wiped out in the Third Age. References to the aviansie in my books suggest that they were a noble race of bird-men, and welcoming to their allies.
7. Balance ElementalJust this Wintumber, a passing adventurer informed me that he'd met and fought a being called the Balance Elemental. Presumably, it is related in some way to the more commonly known Chaos Elemental that stalks the Wilderness. The adventurer did say, however, that as strong and dangerous as this elemental was, it did not appear to mean them any harm, and even spoke to them as if a friend...right before attacking them. How very odd.
8. Tormented demons The same adventurer also informed me of tormented demons, something which I, in my many years, have not even seen hinted at. They were described to me as taller than greater demons, and seemingly in a state of perpetual torment - magically flaying skin and on fire! - which made them even more angry and dangerous than 'normal' demons. Whatever demon realm they were summoned from must have required an immense amount of power to open. As nasty as these demons sound, I'm personally more afraid of whatever brought them to RuneScape...
9. Ket-Zek The ninth strongest beast on RuneScape is, like TzTok Jad, found in the volcano of the TzHaar: the Ket-Zek. It's name roughty translates to either 'guard dog' or...'big hurt'? Hmm, I'm not quite sure that's the correct translation; my TzHaar is a little rusty. Anyway, it is reputed to be a creature with powerful magical and physical attacks, and it is one well worth avoiding.
10. The Inadequacy The Inadequacy. This last 'creature' may be stretching things a little, as it apparently only exists within the dreams of one man. According to this hero, he struggles with this being on a regular basis...but only in his sleep! Thinking about it now, it does sound silly, but he was quite adamant that it was real. Indeed, over his many visits to my library we have become firm friends, and he is not one to lie. Come to think of it, I've not heard from the fellow in some time. I hope all is well with him.
