Rod Reiss' Pure Titan is the largest Pure Titan in the series.
The twelve first-generation Titans were led by the youngest, Kronus, who overthrew their father, Ouranós ("Heaven"), at the urgings of their mother, Gaia ("Earth"). A Titan is about 20 to 30 feet tall.
The reason Reiss was so big was because he was an Abnormal. I believe the the reason Abnormals are created is due to them having a strong enough goal in mind. Reiss wanted to retake the Founding Titan, and the Founder is a powerful titan, so he turned into an Abormal titan twice the size of the Colossal Tian.
The answer to your question is that Armin's colossal titan is NOT larger, both he and Hoover transform into 60m titans. In fact, Bertholdt's colossal titan is arguably larger due to having more initial muscle mass, especially on the chest and core.
Eren was kidnapped by Reiss & brought him to an underground palace. There he ate 'armor' labeled spinal fluid containing bottle.
Again, spoilers, but since Kenny is an Ackerman, he belongs to a different bloodline than most of the other people living within the walls. His bloodline is one of the ones that isn't affected by the Founding Titan's memory altering abilities, and they also can't become titans.
To get there go to Tools > Options > Document Properties . In the Detailing section, there are two options that need to be selected, 'Cosmetic threads' and 'Display annotations'. If you are looking to add a shaded view of cosmetic threads in the hole, the option 'Shaded cosmetic threads' will also need to be selected.
'Some' is plural, so plural form of the word/expression which follows it needs to be used. This applies equally to its derivatives like 'some of the', which also need to be followed by the plural.
Have and has indicate possession in the present tense (describing events that are currently happening). Have is used with the pronouns I, you, we, and they, while has is used with he, she, and it.
