Hi, can anyone help me?, every time I try to print a low-poly pokemon this keeps happening in certain parts of the print
http://postimg.org/gallery/7alj4mcc/1ce3345b/
basically, when it starts to print the tops/tiny areas of the print it would either leave a hole or burn the ABS
thanks
What I usually do is print two models of the same thing. It lets one part cool while the other is being worked on and vice-versa preventing any burning.

Your model is too small so it is staying too hot and literally melting as you print because you are simply adding more and more heat.
As mentioned it may sound like a waste but it has it's reason. Print two or more of very small objects. This gives the layers more time to cool and be at the right temp for the next layer.
If you don't want to print multiples of the same item, you could pick a second item that might give you the same troubles with smaller parts. that way you aren't always stuck printing two of something. You can just pair them up.
what about putting a fan or lowering the extruder temp to 190C would that help? Because its at 200C atm

If you lower the temp or use a fan with ABS that will lead to layer separation and maybe even the part lifting.
We told you what most people who print do to remedy your issue, if for some reason you don't want to follow our advice then you are putting yourself back to the point of when you first asked the question. Because honestly for such a small print there is no alternative. Either print multiples, or print other items of same or taller height so the head can move away from the first model for a few moments.
The only other alternative is to hand edit the gcode and have the head move off to the side for maybe three seconds after each layer is printed. I doubt you want to do as even a small print like this is several thousand lines of code.

Many slicers support that already and will pause printing for a while after each layer if the layer time is less than a certain value. Not sure if cura does but I seem to remember that slic3r did (but I haven't actually used that in a long time now).
Also using a layer cooling fan for small ABS objects is quite common. Yes there is risk of delamination, but blowing softly (low rev fan) on small objects is generally fine, on my experience.
I printed 4 of the same thing and placed them on the corners of my bed and it still burns the same part of the print, any ideas

What speed are you printing those at? If not already there, slow down to 15 to 20mm/s.
its at 30mm/s ill try it on 20 later and is it possible to set the speed by layer or thickness?
You can do lots of things to slow down the print. You can mod g code or with rep host or s3d you can manually override the speed
its a nice .you can see following image

Er, yeah very nice. But I'm not too sure how it helps the o/p.
